Description

Technical Field

[0001] The invention relates to the technical field of drilling sampling, and in particular to a drilling sampling device for detecting engineering construction materials. Background Art

[0002] The drilling sampling device is a device used to obtain soil or other material samples under different geological conditions. It is widely used in tunnel surveys, road inspections, cement-based material sampling and other fields. In the process of paving highway pavement, it is necessary to inspect and sample the pavement. In this process, the drilling sampling device is an important tool. It is mainly used to obtain samples of engineering construction materials for further laboratory analysis and quality assessment.

[0003] During the rotation of the drill barrel of the drilling sampling device, the drill barrel may encounter greater resistance when cutting into the material due to the drill barrel moving too fast or the debris being not discharged from the hole in time during drilling. Especially when the hardness of the drilled material is uneven, the resistance encountered by the drill barrel in different areas will change, which will cause the drill barrel to vibrate or jump unevenly and cause damage to the drill barrel.

[0004] When the drill barrel is impacted or bounced, not only will the vibration caused by the impact be transmitted to the ground and surrounding buildings, causing resonance and resulting in cracks in the road surface, but it will also cause physical damage to the drill barrel or other components, such as cracks, deformation or breakage, which will not only interrupt the work process but may also require expensive repairs or replacements.

[0028] Specifically, when the drill barrel body 35 needs to be driven to rotate, the engine is started, the engine drives the driving pulley 13 to rotate, the driving pulley 13 drives the driven pulley 14 to rotate through the first transmission belt 15, the driven pulley 14 drives the transmission part to rotate, thereby driving the drill barrel body 35 to rotate.

[0029] The above, such as Figure 6As shown, the transmission part includes a driving shaft 17, a driving bevel gear 18, a driven bevel gear 19, a transmission shaft 20, a fixed frame 21, a rotating cylinder 22, a first pulley 23, a second pulley 24 and a second transmission belt 25. The driving shaft 17 is rotatably mounted between the mounting frame 16 and the transmission housing 12. The driving shaft 17 is fixedly connected to the driven pulley 14. The driving bevel gear 18 is rotatably mounted inside the mounting frame 16. The driving bevel gear 18 is fixedly connected to the driving shaft 17. The driven bevel gear 19 is rotatably mounted inside the mounting frame 16. 9 is meshed with the active bevel gear 18, the transmission shaft 20 is rotatably mounted on the mounting frame 16, the transmission shaft 20 is fixedly connected to the driven bevel gear 19, the fixed frame 21 is fixedly mounted on the end of the sliding frame 5 away from the engine body 11, the rotating cylinder 22 is rotatably mounted on the bottom of the fixed frame 21, a first pulley 23 is fixedly mounted on the bottom of the transmission shaft 20, a second pulley 24 is rotatably mounted on the bottom of the fixed frame 21, the second pulley 24 is fixedly connected to the rotating cylinder 22, and a second transmission belt 25 is provided with a tensioning sleeve between the first pulley 23 and the second pulley 24.

[0030] Specifically, as the driven pulley 14 rotates, the driven pulley 14 drives the driving shaft 17 to rotate, the driving shaft 17 drives the active bevel gear 18 to rotate, the active bevel gear 18 engages with the driven bevel gear 19, thereby driving the driven bevel gear 19 to rotate, the driven bevel gear 19 drives the transmission shaft 20 to rotate, the transmission shaft 20 drives the first pulley 23 to rotate, thereby driving the second pulley 24 to rotate through the second transmission belt 25, thereby driving the rotating cylinder 22 to rotate, and the rotating cylinder 22 drives the drill barrel body 35 to rotate.

[0031] like Figures 7 to 10 As shown, the drilling sampling assembly is installed on the sliding frame 5, and is used for drilling and sampling engineering construction materials. The drilling sampling assembly includes an arc guide frame 26, a sliding frame 27, an arc groove 28, a rotating disk 29, a spring 30, a damping part and a drilling part. A plurality of arc guide frames 26 are fixedly installed at equal angles in a circular shape inside the rotating cylinder 22, a sliding frame 27 is slidably installed in the rotating cylinder 22, a plurality of arc grooves 28 are opened at equal angles in a circular shape on the sliding frame 27, the plurality of arc grooves 28 correspond to the plurality of arc guide frames 26 one by one, the arc grooves 28 and the arc guide frames 26 are slidably matched, the rotating disk 29 is rotatably installed inside the sliding frame 27, the spring 30 is fixedly installed on the inner top wall of the rotating cylinder 22, the bottom end of the spring 30 is fixedly connected to the rotating disk 29, a damping part is installed at the bottom of the sliding frame 27 to alleviate irregular vibrations generated during work, and the drilling part is installed at the bottom of the damping part for drilling and sampling.

[0032] Specifically, as the rotating cylinder 22 rotates, the rotating cylinder 22 drives the sliding frame 27 to rotate through the arc-shaped guide frame 26 and the arc-shaped groove 28, thereby driving the vibration damping part to rotate, and then driving the drilling part to rotate, thereby driving the drill barrel body 35 to rotate, and then the drilling sampling can be started. When the drill barrel body 35 contacts the road surface, if the texture of this part of the material is not uniform, it may cause the drill barrel body 35 to vibrate unstably. The setting of the vibration damping part can reduce the influence of this vibration on the drill barrel body 35, ensuring the stability of the sampling process. At the same time, through the cooperation of the arc-shaped guide frame 26 and the arc-shaped groove 28, when the drill barrel body 35 When vibrated, the sliding frame 27 rotates a certain angle in the arc groove 28. At this time, the arc groove 28 slides along the arc guide frame 26. At this time, the drill barrel body 35 will not only have a slight setback, but also move slightly upward along the direction of the column 3. At this time, the spring 30 is compressed, and relative rotation occurs between the rotating disk 29 and the sliding frame 27. Under the elastic force of the spring 30, the coordination between the arc guide frame 26 and the arc groove 28 is not affected, and the normal rotation of the drill barrel body 35 is still not affected, so as to play a role in buffering vibration, maintain the smooth rotation of the drill barrel body 35, ensure that the drill barrel body 35 is not damaged during the sampling process, and improve work efficiency at the same time.

[0033] The above, such as Fig. 9 , Fig.10 As shown, the vibration-absorbing part includes a docking plate 31, a top block 32, a docking frame 33 and a slot 34. The docking plate 31 is fixedly installed on the bottom of the sliding frame 27, and a plurality of top blocks 32 are fixedly installed on the docking plate 31 at equal angles in a circle. The docking frame 33 is rotatably installed on the outside of the docking plate 31, and a plurality of slots 34 are opened in the docking frame 33 at equal angles in a circle, and the plurality of slots 34 correspond one-to-one to the plurality of top blocks 32.

[0034] Specifically, the top block 32 is preferably made of a material with a certain degree of flexibility, such as rubber. As the sliding frame 27 rotates, the sliding frame 27 drives the docking plate 31 to rotate, and the docking plate 31 drives the docking frame 33 to rotate synchronously through multiple top blocks 32 and slots 34. At this time, the top block 32 plays a transmission role, which effectively disperses the vibration energy during the drilling process, further stabilizes the drilling process, and improves the drilling accuracy.

[0035] The above, such as Figure 7 As shown, the drilling part includes a drill barrel body 35, which is detachably mounted on the bottom of the docking frame 33, and also includes a chip groove 36 and a through groove 37. A plurality of chip grooves 36 are provided on the drill barrel body 35 at equal angles in a circular shape, and a plurality of through grooves 37 are provided on the top of the drill barrel body 35 at equal angles in a circular shape.

[0036] Specifically, when drilling holes in the road surface for sampling, the drill barrel body 35 is first installed on the bottom of the docking frame 33. During the drilling process, the chip removal groove 36 will discharge the drilled debris without affecting the continuous drilling. The through groove 37 is provided to allow cooling water to be introduced into the drill barrel body 35 during the drilling process to maintain the temperature of the drill bit stable, prevent the drill bit from being worn due to high temperature, and ensure the drilling efficiency and sample quality. At the same time, after the drilling is completed, a rod-shaped tool can be used to extend into the through groove 37 to assist in the removal of the sample, thereby avoiding the situation where the sample is difficult to remove due to adhesion.

[0037] like Fig.11 As shown, a water spray assembly is mounted on the vehicle frame 1 and is used for spraying water during the drilling process. The water spray assembly includes a drainage frame 38, an annular pipe 39, a water spray head 40, a water inlet pipe 41 and a first joint 42. The drainage frame 38 is fixedly mounted on the vehicle frame 1, the annular pipe 39 is fixedly mounted inside the drainage frame 38, a plurality of water spray heads 40 are installed and connected at equal angles in a circle on the annular pipe 39, the water inlet pipe 41 is connected to the annular pipe 39, the first joint 42 is connected to the input end of the water inlet pipe 41, the first joint 42 is fixedly mounted on the drainage frame 38, and also includes a water pump 43 and a second joint 44, the water pump 43 is fixedly mounted inside the fixed frame 21, two second joints 44 are fixedly mounted on the fixed frame 21, and the two second joints 44 are respectively connected to the input end and the output end of the water pump 43.

[0038] Specifically, during the drilling process, the friction between the drill barrel body 35 and the road surface or soil will generate a lot of heat. In order to prevent it from being damaged due to overheating, reduce the friction between the drill bit and the hole wall, and make the drilling process smoother, it is necessary to spray water during the drilling process. At this time, water pipes are connected to the two second joints 44 respectively, and the water pipe connected to the water inlet end of the water pump 43 is connected to the water source, and the other water pipe is connected to the first joint 42. Then the water pump 43 is started, and the water pump 43 sends water into the first joint 42. The water is discharged into the annular pipe 39 through the setting of the water inlet pipe 41, and is evenly sprayed around the drill bit through the water spray head 40. During the water spraying process, the water in the annular pipe 39 flows through the water spray head 40 to form a uniform water curtain, which effectively covers the working area of ​​the drill bit to reduce the heat generated by friction, while reducing the wear of the drill bit, ensuring the drilling accuracy and efficiency, and can also effectively suppress dust flying and improve the working environment.

[0039] The working principle or usage process of this application is: When using the drilling sampling device to test construction materials, first push the frame 1 to the sampling position, install a suitable drill tube body 35 to the bottom of the docking frame 33, and after fixing the frame 1, connect water pipes to the two second joints 44 respectively, connect the water pipe connected to the water inlet end of the water pump 43 to the water source, and connect the other water pipe to the first joint 42, then start the water pump 43, the water pump 43 sends water to the first joint 42, and the water is discharged into the annular pipe 39 through the setting of the water inlet pipe 41, and is evenly sprayed around the drill bit through the water spray head 40, effectively covering the working area of ​​the drill bit to reduce the heat generated by friction, while reducing the wear of the drill bit, ensuring the drilling accuracy and efficiency, and effectively suppressing the flying of dust, and then the drilling sampling can begin.

[0040] When it is necessary to drive the drill barrel body 35 to rotate, the engine is started, and the engine drives the driving pulley 13 to rotate. The driving pulley 13 drives the driven pulley 14 to rotate through the first transmission belt 15. As the driven pulley 14 rotates, the driven pulley 14 drives the driving shaft 17 to rotate, and the driving shaft 17 drives the driving bevel gear 18 to rotate. The driving bevel gear 18 is meshed with the driven bevel gear 19, thereby driving the driven bevel gear 19 to rotate, and the driven bevel gear 19 drives the transmission shaft 20 to rotate, and the transmission shaft 20 drives the first pulley 23 to rotate, thereby driving the second pulley 24 to rotate through the second transmission belt 25, thereby driving the rotating barrel 22 to rotate.

[0041] As the rotating cylinder 22 rotates, the rotating cylinder 22 drives the sliding frame 27 to rotate through the arc guide frame 26 and the arc groove 28, and the sliding frame 27 drives the docking plate 31 to rotate. The docking plate 31 drives the docking frame 33 to rotate synchronously through multiple top blocks 32 and slots 34, thereby driving the drill tube body 35 to rotate. At this time, the top block 32 plays a transmission role, which effectively disperses the vibration energy during the drilling process. The top block 32 is preferably made of a material with a certain flexibility such as rubber. On the basis of ensuring transmission, the drilling process is further stabilized and the drilling accuracy is improved. At this time, drilling sampling can begin.

[0042] Hold the hand wheel 7 and turn the hand wheel 7 to drive the screw rod 8 to rotate, the screw rod 8 drives the nut 9 to move, and the nut 9 drives the sliding frame 5 to move through the fixed tube 10, thereby driving the drill tube body 35 to move along the column 3, so as to drill the road surface through the drill tube body 35. During the drilling process, the chip groove 36 will discharge the drilled debris without affecting the continuous drilling. The through groove 37 is used to pass cooling water into the drill tube body 35 during the drilling process to keep the drill bit temperature stable, prevent the drill bit from being worn due to high temperature, and ensure the drilling efficiency and sample quality. At the same time, after the drilling is completed, a rod-shaped tool can be used to extend into the through groove 37 to assist in the removal of the sample to avoid the situation where the sample is difficult to remove due to adhesion.

[0043] Furthermore, when the drill barrel body 35 contacts the road surface, if the texture of this part of the material is uneven, it will cause the drill barrel body 35 to vibrate unstably. The setting of the top block 32 can reduce the influence of this vibration on the drill barrel body 35, ensuring the stability of the sampling process. At the same time, through the cooperation of the arc guide frame 26 and the arc groove 28, when the drill barrel body 35 is vibrated, the sliding frame 27 rotates a certain angle in the arc groove 28. At this time, the arc groove 28 slides along the arc guide frame 26. At this time, the drill barrel body 35 will not only have a slight setback, but also move along the direction of the column 3. The spring 30 is compressed and the rotating disk 29 and the sliding frame 27 rotate relative to each other. Under the elastic force of the spring 30, the coordination between the arc guide frame 26 and the arc groove 28 is not affected, and the normal rotation of the drill barrel body 35 is not affected, so as to buffer the vibration and maintain the smooth rotation of the drill barrel body 35, thereby ensuring that the drill barrel body 35 is not damaged during the sampling process and improving the work efficiency. After drilling, the hand wheel 7 is reversed to lift the sliding frame 5 to its original position, and then the sample is taken out of the drill barrel body 35, and the sample can be tested and analyzed.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
